Technetium is placed in the group 7 (manganese group) and period 5 of the Periodic Table of Mendeleev.
Technetium is found in both in a compound and pure forms
Transition metals. in fact, it is the Only radioactive transition metal!
Technetium is not found in nature in appreciable amounts because it has no stable isotopes. It undergoes radioactive decay relatively quickly, making it rare and short-lived in the Earth's crust. Any technetium present on Earth is likely formed as a byproduct of nuclear reactions or artificially created in laboratories.

Technetium is not a naturally-occurring element; it was created in a laboratory.
Technetium is a man made element; natural technetium exist only in ultra traces in uranium deposits.

No, Technetium does no occur naturally on earth except in trace amounts in molybdenum deposits.
Technetium exist in infinitesimal traces in some uranium ores. Being radioactive and unstable technetium was lost from the Earth by decay.

The name technetium comes from the Greek word that means "artificial." A link can be found below.
Technetium was discovered by Emilio Segre and Carlo Perrier in 1936 at the University of Palermo, Sicily, Italy.

No. Almost all technetium is man made. In nature it is found only in trace amounts mixed in uranium or platinum ores.
